'To all whom it may concern.'

Be it known that I, EDWARD C. HARVEY,

a citizen of the UnitedStates, residing at Franklinton, inthe parish ofl Washington andState of Louisiana, have invented cer` tain new and useful Improvements in C'ultiA vators, of which the following is a specification.

vators and harrows, and has for one of'its objects to increase the efliciency and utility of devices of this character.

Another object of the invention is to pro' vide a device of this character comprising a rigid supporting frame enlarged toward the rear and with means for coupling cultivator or harrow teeth alternately thereto without changing the supporting frame.

With these and other objects in view, the invention consists in certain novel features of constructionl as herein shown and described and specifically pointed out in the claims, and in the drawings illustrative of the preferred embodiment of the invention.

Fig. 1 is a plan view ofthe improved implement. v

Fig. 2 is a side elevation.

Fig. 3 is an enlarged sectional detail on the line 3 3 of Fig. 1.

Fig. 4 is a rear elevation of the "parts shown in Fig. 3.

Fig. 5 is a sectional detail illustrating the manner of coupling a conventional culti; vator standard and shovel to the'implement.

The 'improved implement is adapted to support harrow teeth or cultivator standards of various forms, and includes a main supporting frame formed from a single bar, preferablyT of channel steely and bent intermediate the ends to form ashorttransverse portion 10 and rearwardly extending portions 11. the latter in spaced parallel relation, as shown in Fig. 1. l

Rearwardly of the portions 11 thebar is directed in reversely diverging sections each formed of alternating longitudinal portions 12 and transverse portions 13, or in step like order, as shown* in Fig.y 1.

At their rear ends the diverging portionsv of the frame are rigidly coupled at 14 by a spacer bar or brace member 15, the latter having a rearwardly extending central loop 16.

Obliquelydisposed braces 17 are also arranged between the b race` 15 and the dL This invention relates to combined culti-` vverging side members, vtofreinforce and strengthen the connection.

A 'clevis device of suitable construction Maries is attached-to the forwardly convergingv portion of the frame to receive the'draft appliance.

By this means a strong and rigid frame is produced which will not yield under the severe strains to which it willbe subjected" when in use. y

Attached to the rear face of thejportions 10, to each of the portions 13, and to the forward face of the loop 16, are keeper vrnem bers 18 in spaced vertical relation, each vertical pair of the keepers adapted to support a harrowv tooth 19, as shown in Figs. 1, 2, 3, and 4, or to support a cultivator standard, as shown at 20 in F ig. 5, as'may be required. Supported in each vertical pair of the keepers is a bearing plate21 against which clamp screws 22 tapped through the rear ofthe keepers engage. By this means theteeth or standards lmay v vbe firmlyv and adjustably clamped in position.`

By arranging theframeside members in step like order, the'teeth 19 'or cultivator` shovels do not trail, but each forms its own furrow and thus the soil.

The harrow teeth or cultivator standards operates uniformly 0n The frame member will be constructed from. channel metal, as aforestated, 'and preferablyy of steel, and as light as possible consistent with the strain to which it will be subjected. v

.The preferred embodiment of the invention is disclosed in the ldrawings and set forth in the specifications, but it will'be kunderstood that modications within the scope of the claimsmay be made iu the' construction without departing from the principle of the invention or sacrificing any of its advantages. v

Having thus described is claimed as new is f 1. A lcultivator frameformed from a single bar bent intermediate the ends to form a transverse portion and Yrearwardly directed the invention, what versely diverging, the dverging portions be- S5 may be alternately coupled to the frame'j l ,thus quicklyV transforming the device from a portions in spaced parallel relation, and thence directed rearwardly and re- 10 the diverging portions formed with alternating longitudinal and transverse portions7 a, transverse brace member connected to the rear ends oit the divergng portions of the bar, means for coupling earth engaging devices to said transverse portions, and means for coupling an earth engaging device to said transverse coupling member.

In testimony whereof, l aiix my signature hereto.

EDWARD C. HARVEY.
